Answer 2

Answer:

The magnetic force per unit length experienced by wire C is $\frac{5}{6} \frac{\mu}{2\pi} \frac{I_{1} I_{2} }{d} N$

Explanation:

Step 1: Prerequisite Knowledge

The magnetic force per unit length experienced by two parallel wires is $\frac{\mu}{2\pi} \frac{I_{1} I_{2} }{d}$

Step 2: Calculation

Force on wire C is due to both wire A and wire B since the direction of magnetic current is the same in both of the wires so force per unit length will add up.

Total force per unit length is= force due to A on C + force due to B on C

$F_{net}=} \frac{\mu}{2\pi} \frac{(I)(I)}{3d} + \frac{\mu}{2\pi} \frac{(I)(I) }{2d}$

$F_{net}=\frac{5}{6} \frac{\mu}{2\pi} \frac{I_{1} I_{2} }{d} N$
